Glossary: (+)-cis,cis-nepetalactol = (4aR,7S,7aS)-4,7-dimethyl-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran-1-ol
(+)-cis,trans-nepetalactol = (+)-iridodial lactol = (4aS,7S,7aR)-4,7-dimethyl-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran-1-ol
Other name(s): NEPS1 (gene name)
Systematic name: nepetalactol:NAD+ 1-oxidoreductase
Comments: The enzyme, characterized from the plant Nepeta mussinii, binds an NAD+ cofactor. It also catalyses the activity of EC 5.5.1.34, (+)-cis,trans-nepetalactol synthase.
